with over 45 years experience in quality/inspection/NDT etc in an oil and gas refining industry ,I consider the material presented here to be super professional . Congratulations on your vast knowledge and experience and the clarity of your articles .

I love your think your charts are some of the best I have seen. One favor i would ask is that I would like your permission to use your material for non profit training of young people in the our field would appreciate though if you could send me clearer copies of your charts

At 64 and retired I want to give back and pass on as much of my knowledge to the younger folk .
